The parameter information of operation；The parameter information of non-visual operation is parsed using key；Reduce the content of target area 2.It is non-can
, can be with the different operating type such as mosaic processing or Fuzzy processing depending on the action type of change.If non-visual operation
(for example dynamic password is encrypted) is encrypted in ciphering process and is treated for parameter information, then according to during encryption
Processing is decrypted in it to secret key pair, then can obtain the parameter information of non-visual operation, so as to carry out reducing the mesh
Mark region 2.If the parameter information of non-visual operation is not encrypted, user is visual using originally non-
The parameter information of the operation of change can be reduced to target area 2.
In a preferred embodiment, decryption processing also includes：By biological information with obtain encrypted image it is commutative
Image file information is compared, and only allows to operate encrypted image when comparison result is identical.When at encryption
During reason, after biological information is entered into the exchangeable image file information of encrypted image, in decryption processing, it is necessary to user
The exchangeable image file information of encrypted image of the biological information with obtaining is compared, and just allows when comparison result is identical
Encrypted image is operated, for example, restoring operation is carried out to encrypted image target area 2, it is achieved thereby that to encrypted image
Further protect.
Fig. 6 shows the structured flowchart of the device of the image security of the embodiment of the present invention.As shown in fig. 6, image security
Device includes processor 3 and memory 4, and processor 3 is connected with memory 4, and processor 3 is when image 1 is encrypted
Perform：Content recognition is carried out to image 1；According to the target area 2 in the result selected digital image 1 of content recognition；To target area 2
Non- visualization processing is carried out so that image 1 forms encrypted image, and generates corresponding key, wherein key is used for non-visualization
Target area 2 carry out restoring operation；Memory 4 preserves key and encrypted image.
By recognizing the image 1 with sensitive information, the local target area 2 including sensitive information is carried out non-visual
Change is handled, and can cover local sensitive information, protect the sensitive information of user, and for the non-target area of image 1
The part of domain 2 does not make non-visualization processing, and user can be made quickly to understand the information of the image 1, so that encrypted image can be safe
Storage beyond the clouds.
Preferably, image 1 is carried out before content recognition, user can will wish the information or other sensitive informations of secrecy
Preserved, after content recognition is carried out to image 1, if it find that the recognition result of the content of image 1 has the letter with preservation
Identical content is ceased, then to the region including sensitive information, i.e. target area 2 carries out non-visualization processing.
In one embodiment, if not recognizing the need for the sensitive information of secrecy according to the result of content recognition,
Target area 2 is not present in image 1, this image 1 need not carry out non-visualization processing.
In another embodiment, processor 3 is in encryption process, before content recognition is carried out to image 1
It can also carry out and judge whether to open safe mode.If result is yes, processor 3 performs foregoing step.If result
It is no, then memory 4 carries out preservation processing to image 1.
Non- visualization processing is carried out to target area 2 in above-described embodiment, can be that mosaic is carried out to target area 2
Processing or Fuzzy processing.Wherein, the formation of image 1 encrypted image, can be that mosaic processing or fuzzy is carried out to target area 2
Image after change processing, the key of generation is the parameter that mosaic processing or Fuzzy processing are utilized when encrypting the image 1
Or algorithm.Preferably, the key of generation can also be the key further encrypted to above-mentioned parameter or above-mentioned algorithm.Wherein, enter
The process of one step encryption can be realized using the technology of symmetric cryptography or asymmetric encryption.
In a preferred embodiment, when memory 4 preserves encrypted image, by biological information be entered into encrypted image can
In swap image fileinfo, the biological information in exchangeable image file information can be for further protection encrypted image.
Fig. 7 shows the structured flowchart of the device of the image security of another embodiment of the present invention.As shown in fig. 7, image
The device of secrecy also includes the display 5 being connected with processor 3, and processor 3 is performed when processing is decrypted to image 1：Obtain
Take encrypted image and key；Encrypted image is identified to obtain target area 2；Utilize the non-visual target area of secret key pair
Domain 2 carries out restoring operation, to decrypt encrypted image；Image 1 after the display decryption of display 5.
In a preferred embodiment, processor is in decryption processes, and after encrypted image 1 is obtained, execution is sentenced
It is disconnected whether to open safe mode.If result is yes, foregoing step is performed.If result is no, display is to image 1
Shown.
In another embodiment, processor 3 carries out execution during restoring operation：Judge non-visual action type；
The parameter information of non-visual operation is determined according to action type；The parameter letter of non-visual operation is parsed using key
Breath；Reduce the content of target area 2.Wherein, non-visual action type, can be with mosaic processing or Fuzzy processing etc. no
